(57) [Summary] [Object] The present invention relates to a processing composition used for a diffusion transfer product such as a diffusion transfer photographic film unit, and to a diffusion transfer photographic product using the same. A specific thickening agent is used in the treating composition of the present invention, and the thickening agent is selected from the group consisting of (a) acrylic acid, methacrylic acid, ethacrylic acid, propacrylic acid and butacrylic acid. Carboxylic acid monomer, and (b) formula (Wherein R 1 and X are as defined in the specification) consisting of a copolymer polymerized from a monomer system consisting of a hydrophobic monomer, Phase separation of the treating composition by use (pooling (po oling)) is avoided. |
